Tb aZ Z vhomt't may concern;

Be it known that I, JOB A. D1L o'N,a,

native-born citizen of the United States, re

siding at Tecumseh, in the county of-Johnson and State of Neb1'aska,:have invented certain new and useful"Improvements in Clamps, of which thefollowing is a specification, reference beinghad to the accompanying drawings.

This inventlon relates to clamps, and particularly to clamps which are adapted foruse in connection with wire stretchers to hold the wires of a fence while they are being stretched. 1

An object of this. invention is the provision of a clamp of this character which comprises a pair of bars having registering openings formed therein to receive the bolts upon which the clamping nuts are mounted, means being provided whereby one of the bars may be removed or applied to the bolts without disengaging the bolts from" the A. further object of this invention is the provision of a clamp of this character which comprises a Ipair of bars, one of the bars' having a p urality of circular openings thereinand be other bar having a plurality of elongated openlngs thereinwhich register with the circular openings in the first bar, the registering, openings being adapted to receive bolts upon which the clamping nuts are mounted, each of the bolts having one end angularly disposed so that the same may be turned to allow the bar having the elongated openings to be passed over the angularly disposed portions of the bolts without disengaging the bolts from the bar having the circular openings therein.

With these and other. objects in view, my invention consists in the novel construction, combination, and arrangement of parts to behereinafter more fully described, claimed,

and illustrated in the accompanying drawing. in which, i Figure 1 is a rear elevational view of my improved clamp; Fig. 2 is a front elevational view thereof; and Fig. 3 is a sectional View on the line 33 of Fig. 2. t

Referringlnore particularly to the drawing, the numerals 1 and 2 designate a pair of clamping bars which are adapted for use in connection with awire stretcher of any desired construction, to grip the wires of a fence therebetween, the bar 1 having a plurality .of horizontally disposed circular Specification of Letters Patent.

openings 3 formed" therein, andthebarQ.

havinga plurality of elongated openings or slots l formed therein which-are spaced the same distance apartjas the openings 3rin the bar 1 to register rtherewith. Disposed through the openings 8 in the'bar 1 are bolts 5 .which are threaded as at '6, at one end to receive the nuts 7 which" are provided with turning handles 8, the other end of each bolt being provided with an angular extension 9,

the extension 9 'beingof ale'ngth slightly less than the length of the elongated openings 4 in the bar 2 so that the bolts-may be turned to dispose the extension 9 longitudinally of the bar 1 whereby the bar 2 maybe engagedagainst the bar 1 by passing the slots 4 over the extensions 9 of the bolts.

The bar 2 is provided on its outer face with transversely extending grooves .10, each groove extending across one of the slots 4:

- at its upper end, one end of each groove being adapted to receive the angular extension of one of the bolts after the bar 2 has been engaged against the bar 1 to prevent accidental separation of the bars.-

- In the practical use of my improved clamp, when it is desired to connect the same to the wires of a fence, the bar 2 is disengaged from the bar 1 and the bar 1 is placed so that the wires engage the inner face of the bar, whereupon the bolts are disposed so that the extensions 9 thereof extend longitudinally of the bar and the bar 2 is engaged against the wires with the bolts projecting through the, slots 4:." In

this position, the bolts are turned so that the extensions 9are disposed transversely of the bar 2 to engage in one end of the grooves 10, whereupon the nuts 7 are tightened against the outer face of the bar:1 to

securelyclamp thewires of the fence between'the bars. In the usual construction of wireclamps for stretchers, two men are necessary to operate the same, one to hold the bolts toprevent them from turning while the other turns the nuts tightly against one of the bars, while in a clamp constructed in accordance with my invention, one man can easily operate the device to clamp the wires of a fence betweenthe bars as the grooves 10 in which the extensions 9 of the bolts enof'the bolts, while the being turne I flush against the outer gage prevent turnin nuts are face of the bar 1. The bolts used in con nection with clamps of ordinary construc-' tion must also be entirely removed" from the bars when the same is separated While in my improved clamp it will be seen that the bolts are always carried by the bar 1 having circular openings therein, so that all danger of the bolts becoming lost or misplaced is obviated.

Having thus fully described my inven tion what I desire to claim and secure by Letters Patent, is

A clamp of the character described C0111- .prising a pair of bars, one of said {bars having a circular opening therein, the other of said bars having an elongated opening therein for registrationwith the opening in the first mentioned bar, a bolt having a laterally disposed head arranged through said registering openings, said second mentioned bar having a transversely disposed groove formed in its outer face and crossing said elongated opening at one end thereof, said groove being adapted to receive the head of the bolt when the bars are connected-together, so that the head is maintained out ofalinement with the elongated opening.

In testimony whereof I hereunto affix my signature in the presence of two witnesses. JOB A. DILLON. Vitnesses: i A. W. BUEFUM, DhB. PARKER.
